The air-conditioning industry is welcoming the frequency conversion era. Who is the main ups and downs? In 2008, it took the lead in popularizing the popularization of inverter air conditioners, and promoted the inverter air conditioner to become the protagonist of today's protagonist. It made a clear answer to the technical direction of inverter air conditioners in the future. In the next 3-5 years, Midea will do all around frequency conversion technology. Azimuth strategic layout, in the direction of energy-saving-environment-intelligence-comfort-health, from the core component planning, patent protection and other dimensions to enhance the leading position of the US inverter technology, and then lead the global inverter air-conditioning technology development direction. Energy-saving: the eternal goal of the development of the US inverter air-conditioning technology In 2010, the US-developed D-type frequency conversion splitter, the seasonal energy efficiency ratio was 7.33, reaching the world's first, 40W minimum operating power also set the lowest record in the world's air-conditioning history. In the next few years, Midea will make full use of powerful compressor R&D capability, motor R&D capability and complete machine design capability to pursue high SEER and high APF as its own responsibility, and develop more energy-saving inverter air conditioners. In 2015, the frequency conversion season energy efficiency ratio will be realized in 2010. Based on the increase of more than 50% on a year-by-year basis, the cooling and heating capacity of a frequency conversion hang machine has reached the current level of 3 fixed speed cabinets, achieving 0.1w ultra-low power standby, taking the lead in setting off the energy-saving banner of Chinese household appliances. Environmental protection: Midea always adheres to technological achievements. With its years of technical accumulation and technical cooperation, the company has achieved unprecedented breakthroughs in research on new environmentally friendly refrigerants such as R290, R32 and R161. The R290 project has become a demonstration of the US Multilateral Fund with a support of US$4 million. project. The advent of the beautiful Q-HAP solar inverter air conditioner has broken the technical gap of the global solar air conditioning project. In the next five years, Midea will completely abolish the use of R22 refrigerant, and carry out project promotion in the form of a comprehensive basic research platform, school-enterprise cooperation, joint development, etc., through different refrigerant physical properties, thermal analysis, system matching, heat exchanger technology. Research on parts replacement technology, development and use of new and safer environmentally friendly refrigerants. At the same time, the use of solar energy technology in other series of products is popularized, and research and development in other new energy sources are promoted. Intelligent: realize the full intelligent technology of inverter air conditioner within three years. The focus of beauty is to improve the intelligent level of inverter air conditioner from the aspects of human technology, human-machine dialogue and Internet of Things, and to increase the investment and research of self-learning function of inverter air conditioner. Within three years, realize the productization of inverter air conditioner full intelligent technology in inverter air conditioner, relying on the use of various intelligent sensors, the improvement of control algorithm, the application of Internet of Things technology, and the perfect real-time dialogue function, allowing users to truly experience anytime, anywhere, whatever they want. . Comfort: The guide of comfort technology and the research on the comfort of the inverter technology, the first time to put forward the user's sensory satisfaction as the standard, in low noise, three-dimensional air supply, anti-cold overheating technology, air volume radiation, ultra-sensitive, humidity control In-depth research and improvement in ultra-high cooling and heating capacity, achieving precise temperature control of 0.1 degrees Celsius in the next three years, ±0.1HZ frequency control, 1-150HZ ultra-wide frequency range operation, -25°C~55°C degree The wide temperature range operates to enhance the user's comfort and promote the establishment of national air conditioning comfort standards. Health: to create the healthiest environment for consumers In the current inverter air conditioner products, the use of filter screen dust, ion sterilization, ventilation and other health functions have begun. In the future, the United States will continue to increase its focus on health. In three years, sterilization and dust removal and healthy ventilation technology will be written into the enterprise standard as the standard for inverter air conditioners; indoor air quality (IAQ) will become the next key research object of the US inverter air conditioner. , to give users a fresh and healthy environment. At present, Midea has become one of the world's largest manufacturers of household air-conditioning products. In 2010, it produced 30 million sets of global production and sales. It has world-class production equipment and testing equipment, and its key equipments are from the United States, Europe, Japan and other regions. Or the introduction of the country; and established joint research and development laboratories with international companies such as Toshiba Carrier, IR, Fairchild, Sanyo, etc.; and introduced high-level technical experts and suppliers from Europe, America, Japan and South Korea, and has two overseas productions in Vietnam and Egypt. The base and five major domestic production bases such as Shunde, Guangzhou, Wuhan, Handan and Wuhu. We are going to use inverter air conditioners as an opportunity to reverse and finally establish the right of Chinese companies to talk about global air-conditioning technology and product trends. Wu Wenxin, president of Midea Refrigeration Appliance Group's home air-conditioning business unit, said that promoting the popularity of inverter air conditioners is only the first step, the ultimate of beauty. The goal is to establish a right to speak on the future development trend of the industry in the global white electricity market. The breakthrough is to build a new industrial system that is conducive to Chinese enterprises through new technology products.
Self-aligning Ball Bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available open or sealed.
The bearings are insensitive to angular misalignment of the shaft relative to the housing , which can be caused, for example, by shaft deflection.
Bearing features Self-aligning Ball Bearings Self-Aligning Ball Bearings,Precision Self-Aligning Ball Bearing,Self-Aligning Double Row Ball Bearings,Double Self-Aligning Ball Bearing Ningbo Ritbearing Imp & Exp Co.,Ltd. , http://www.ritbearingchina.com
Accommodate static and dynamic misalignment
The bearings are self-aligning like Spherical Roller Bearings or CARB bearings.
Excellent high-speed performance
Self-Aligning Ball Bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.
Minimum maintenance
Due to low heat generation the bearing temperature is lower, leading to extended bearing life and maintenance intervals.
Low friction
Very loose conformity between balls and outer ring keeps friction and frictional heat at low levels.
Excellent light load performance
Self-aligning Ball Bearings have low minimum load requirements.
Low noise
Self-aligning ball bearings can reduce noise and vibrations levels, for example, in fans.
